Flash 10.0 marked the final major release for PowerPC Macs. While
[Flash 10.1][1] can run on PowerPC Macs, it runs rather poorly on
these machines compared to 10.0.

However, a few Flash applications require 10.1. Fortunately, the
standalone players can co-exist with different versions if the use is
needed.

The first download is the standalone app, dated to October 2009.

The second download is all of the internet plugins, also dated October
2009.

The third download is updated plugins, dated to February 2010.

A matching standalone app for Feb 2010 has not been found yet,
unfortunately.

Compatibility
Architecture: PPC x86 (Intel:Mac)

Mac OS X 10.4 Tiger and up
